ausearch_add_interpreted_item

AUSEARCH_ADD_INTERPRETED_ITEM(3)				  Linux Audit API				  AUSEARCH_ADD_INTERPRETED_ITEM(3)

NAME

       ausearch_add_interpreted_item - build up search rule

SYNOPSIS

       #include <auparse.h>

       int ausearch_add_interpreted_item(auparse_state_t *au, const char *field, const char *op, const char *value, ausearch_rule_t how);

DESCRIPTION

       ausearch_add_interpreted_item  adds  one search condition to the current audit search expression. The search conditions can then be used to
       scan logs, files, or buffers for something of interest. The field value is the field name that the value will be checked for. The op  vari-
       able describes what kind of check is to be done. Legal op values are:

	      exists
		      just check that a field name exists

	      =
		      locate the field name and check that the value associated with it is equal to the value given in this rule.

	      !=
		      locate the field name and check that the value associated with it is NOT equal to the value given in this rule.

       The value parameter is compared to the interpreted field value (the value that would be returned by auparse_interpret_field(3)).

       The  how value determines how this search condition will affect the existing search expression if one is already defined. The possible val-
       ues are:

	      AUSEARCH_RULE_CLEAR
		     Clear the current search expression, if any, and use only this search condition.

	      AUSEARCH_RULE_OR
		     If a search expression E is already configured, replace it by (E || this_search_condition).

	      AUSEARCH_RULE_AND
		     If a search expression E is already configured, replace it by (E && this_search_condition).

RETURN VALUE

       Returns -1 if an error occurs; otherwise, 0 for success.
